Answer:

B

Step-by-step explanation:

[tex] \frac{1}{40} + x = \frac{1}{8} [/tex]

[tex]40( \frac{1}{40}) + (40)x = 40( \frac{1}{8} )[/tex]

[tex]1 + 40x = 5 \times 1[/tex]

[tex]1 + 40x = 5[/tex]

[tex]40x = 5 - 1[/tex]

[tex]40x = 4[/tex]

[tex] \frac{40x}{40} = \frac{4}{40} [/tex]

[tex]x = \frac{1}{10} [/tex]
